Yukon Gear High Performance Gear Set For GM 8.5in & 8.6in in a 5.38 Ratio

If you're looking to re-gear your differential to handle significantly larger tires or a substantial increase in horsepower, this Yukon Gear & Axle high-performance ring and pinion set is a solid choice. Designed for GM 8.5-inch and 8.6-inch rear axles, this set features a 5.38 ratio, which is ideal for applications where you need more torque multiplication, such as off-roading or towing with larger tires. This ratio helps bring your engine's RPMs back into an optimal range after modifications.

Yukon engineers put a lot of thought into these gear sets. They use high-grade steel for both the ring and pinion gears, and the tooth surface finish is specifically designed to reduce friction and heat buildup. This is crucial for longevity, especially under high torque conditions or during long races. The fitment is designed to OEM specifications, meaning it should integrate well with your existing differential housing, though it's important to note that this specific set requires a notched driveshaft for installation.

This gear set is a significant upgrade for a wide range of GM vehicles, from classic trucks like the Chevrolet C10 to modern SUVs like the Cadillac Escalade. Yukon Gear & Axle stands behind their products with a 1-year warranty against manufacturing defects, and they also offer an optional Y.E.S. Plan for lifetime coverage. Proper installation by a qualified technician is recommended to ensure optimal performance and durability.
